1 Claim. 1

My application is a division :of 'my copending application Serial No. 585,152, filed March .27, 1 945, and entitled Parking Meter and Coin .Slot Therefor .divided'into this'application, and copending applications Serial Nos. 684,579; 684,580; and 684,582.; "and the invention relates to parking meterspfor use along streets, roadways and in conjunction with vehicle stalls and parking areas for example.

An object of my invention is the provision or a simple, practical and inexpensive parking meter of rugged construction having cam feed means, forming an integral and essential part of the same, which is adapted for setting timing mechamsm of the apparatus to initiated position while feeding a coin.

Another object is to provide a device of the character indicated wherein driving energy for included set-initiated timing means is stored as an incident to the time-setting operation and in which energy imparted to coin feeding means of the meter is stored for driving the meter timing means.

Another object of my invention is the provision; in' a device of the character indicated, of timing "apparatus for selective setting to measnreanyone of several diiferingperi'ods of time corresponding to different coin values payable to the meter.

Other objects in part will be obvious and in part referred to hereinafter.

' Theinvention accordingly consists in the combination of elements, features of construction and arrangement of parts as described herein and particularly set forth in the claims at the end of this specification.

In the accompanyingdrawings, in which like reference characters denote like parts throughout the several views, there is illustrated a parking meter embodying certain features of my invention.

Figure 12 is a side elevation view corresponding to Figures fi, '7 and 8.

Referring now, more particularly, to the prac tice of my invention, attention is directed to the drawings, notably Figures 1 and-2. The meter will be seen to comprise an external housing [0 (Fig. 1) into which is seated a housing door H. The door is held in place by a screw type lock l2 which engages with post i3 fixed into the housing as best illustrated in Figure v2. The upper part of the door is cut away toprovide a glass window I 4 for revealing a time indicator and signal plate which is to be discussed in detail later. A similar window for revealing a like time indicator and signal plate is provided in the back of the housing. In the housing door H there is a coin window l6 which displays, from inside, the last coin which has served to set the meter. A coin receiver 33 for manipulation in setting the meter extends through the right hand side of the housing (Fig. 1). The lower portion 1 of the housing comprises a coin deposit chamber l8 for receiving coins after display of the same at window I6. The housing is sturdily reinforced with reinforcing ribs I9 and on inside walls is shaped to conform with the curvular edges of face plates 20, 20a and 20b (shown in Figs. 6, 8 and 12) so that the meter mechanism is firmly held in place in the housing without necessity for bolting and yet is easily removed.

' hereinafter.

In Figure 5, substantially all frame work, face plates, housing, and the like, of the meter have been omitted to facilitate a clearer understanding of certain features of my invention. The

mechanismillustrated is adapted for receiving a transmitted along shaft 34 to sector gear 35 which in turn causes gear 36 and pinion 31 to rotate clockwise driving rack 38 to the right as indicated by arrow in Figure 5. The rack 38 is guided during movement by guide rod 39 whose position is fixed.

The coin carrier or slide 40, composed of two parallel plates 4I connected by lugs 42 and 43 moving in slot 44 (Fig. 6) provided in parallel face plates 20a and 2012 (Figs. and 12), is rigidly attached to rack 33 by connecting plate I45. The plates 20a and 20b form the walls'of a compartment for the actuating coin as appears more fully hereinafter. A bottom plate 2011. between the plates 20a and 20b adjacent slot 44 (see Fig. 6) forms a floor or track for supporting the coin during the carrying action. As the rack is driven to the right, so is the slide such that when coin receiver 33 has moved down through the entire path of its arc, the coin slide has moved in synchronism to its extreme right hand position. At this point the coin is discharged from the receiver (this will be described in detail later) and drops between plates 20a and 20b and onto bottom of track 200 to seat just in front of lugs 43.

Now that the coin is deposited, pressure is released on the coin receiver 33. Since the previously described action was accomplished under spring tension exerted by springs 45 and 46, when pressure on the coin receiver is released, the op posite motion automatically tak s place; that is, provided the receiver 33 is relinquished, shaft 34 and sector gear 35 move clockwise, gear 36 and pinion 31 move counterclockwise thus driving rack 38 and slide 40 to which it is connected, to the left. As the coin slide moves to the left, lugs 43 carry-the coin forward with it.

A nickel and a penny cause finger plate 53 to be rotated preferably as a, part of the timing mechanism: the nickel by engaging post 41 retates rear lever arm 48 which by coming in contact with post 52 rotates finger plate 53 through its entire arc, setting indicator pointer 56 at sixty minutes; while the penny by virtue of its smaller diameter fails to contact post 41 and consequently moves forward an additional distance to rider lug before actuating the linkage so that finger plate 53 rotates only one-fifth as far moving the indicator pointer only up to the twelverninute calibration. If additional pennies are deposited up to five, the same operation is repeated as described above except in the instance of a second penny the wedge shaped finger pawl 69 engages second tooth 8| of finger plate 53 and the flange 84 on limiting lever 83 engages the second tooth 83 of limiting finger plate 86; the third penny causing the third tooth on each plate to be engaged, etc. All of the setting actions are achieved only after manual power has been expended and thus are free of any eXternalforC- ing by the person depositing the coin.

So now the finger plate 53 and indicator pointers 56 are positioned according toactual coin ,value deposited. This rotation has. in turn been I back through a counterclockwise rotation to the zero setting at a velocity required to traverse the distance back to the zero setting in the time indicated. In the event that the clock mechanism 9| is still operating when the indicator pointers have returned to zero and is there restricted to any furthermovement by shoulders 93 on time indicator plates 53, the clock mechanism is permitted to continue operating until it has run down by the slip clutch 92.

The clock mechanism BI is provided with driving energy automatically as in the following manner: Attached to the left hand end of rack 38 and projecting to the rear is a lever 94. This lever is shaped substantially as shown in Figures 5 and 8 and is engaged with post 95 on arm 96 which is connected with sector gear 97. Arm 96 and gear 91 are free to rotate about pin 98. M eshed with gear 3'! is another sector gear 99 which delivers winding torque to a suitable clock spring (not shown) of the meter timing mechanism as by means of shaft I00. The winding operation is: accomplished as follows: As a coin is fed through the receiver 33 on the in stroke, shaft 34 is rotated by the forward motion, sector gear 35, gear 36, and pinion 31 driving rack 38 to the right as described previously. This motion also carries lever 94 to the right thereby rotating post 35, arm 65 and sector gear 01 in a countel-clockwise direction about pin 98. Being meshed with sector gear 93, the latter and shaft Hill are driven clockwise through an angle sufficient to wind or store energy in the clock spring enough for driving the timing mechanism in excess of one hour. As the spring runs down driv ing the paid-for timing operation, sector gears 91 and 99 and their appendages rotate back to their initial positions. Although other arrangements in accordance with the invention are contemplated, it will be noted, in connection with the present embodiment, that the clock mechanism is wound the same amount whether a nickel or a penny is deposited.

To explain the details and operation of a time indicator plate 53 and its mechanism, attention is directed to Figures 9, 10 and 11. The time indicator plate is shaped as indicated in Figure 9 and is provided with arow of nine rectangular slots separated by a space equal to the width of the slots. The top edge of the time indicator plate is curved, the curve extending to shoulders 93 and I6I, one on each side, whose function is to limit the sweep of the indicator pointer-56. The upper-face of the time indicator plate 58 is calibrated from one to sixty minutes to show the number of minutes of parking time remaining. The time indicator plate 53 is affixed to the mechanism by being screwed to posts I02 as shown in Figures 5, 6, 7 and 12. Mounted behind the open slots I04 of time indicator plate 58 is signal plate I03 which is held in position by posts I05 (Fig. 11) which protrude through slots I06 and whose purpose it is to guide the lateral movement of the signal plate IE3 and limit its travel as well as to register the position of the signal rectangular slots I04 in time indicator plate 58.

This position is illustrated in Figure 9. When the signalplate is moved to its extreme right hand position as shown in Figure the word Violation" appears through slots I04.

After a coin has been deposited and an indicator pointer 56 has moved to some position such as shown in Figure 11, the signal plate I03 moves to the right (note that these directions will be opposite from those described in Figures 9 and 10 as Figure 11 is a rear view) by spring tension from spring I0I. In this position Parking Fee Paid is displayed as illustrated in Figure 9. After the time paid for elapses and the clock mechanism has returned the time indicator pointer 56 to zero position, the pointer contacts upper lever arm I08 which rotates about pin I09 as does lower lever arm IIO which is connected to the upper lever arm I00. This rotation causes the lower lever arm to move clockwise as seen in Fig. 11 and engage post III which is fixed onto signal plate I03. As post III, and likewise signal plate I03 are moved to the left against tension of spring I01, the word Violation appears in the rectangular slots I04 in time indicator plate 58 (see Fig. 10). The Signal plate remains in this position until another coin is deposited, at which time indicator pointer again moves to the left and the above described operation is repeated.

As many possible embodiments may be made of my invention and as many changes may be made in the embodiment hereinbefore set forth, it is to be understood that all matter described herein, or shown in the accompanying drawings, is to be interpreted as illustrative and not as a limitation.

I claimi In apparatus of the class described, in combination, a face plate having a timing scale thereon and a multiplicity of openings therein, a cooperating back plate slidably mounted on the back of said face plate having thereon two sets of legends for alternate display through said openings in said face plate, pring means urging said back plate in one direction for displaying one set of legends through the openings of said face plate, lever means pivotally mounted on the back of said face plate for moving said back plate in another direction for displaying the other set of legends through the openings of said face plate, and a timing pointer movable over said timing scale of said face plate and contacting said lever mean at one extreme position thereof to move said back plate against the action of said spring means to display said one set of legends and releasing said lever means and back plate to the action of said spring means, in being moved away from said extreme position, to display said other set of legends.
